Russia's grip on Kaliningrad weakens despite nuclear saber-rattling

The Kremlin has confirmed Russia's intent to use its 'entire weapons arsenal' to defend Kaliningrad if threatened, while denying explicit nuclear threats. Concurrently, multiple analyses suggest Russia's nuclear deterrence credibility is eroding despite repeated rhetoric, potentially emboldening adversaries. The ambiguity of 'entire arsenal' leaves nuclear use unresolved, but the perceived weakening of deterrence introduces strategic instability.
